. EYEGLASS-MOUNTING.

,and useful Improvements in Eyeglass ltlountings; and I do herebydeclare the following to be a full, clear, and exact desoription of thesame,--reference being had to the accompanying drawings, 10'

forming apart of this specification, and to the reference numeralsmarked thereon.

The present invention relates to eyeglass mountings and this applicationis a division of an application filed by me on June 2-1, 1907, SerialNo. 380,027.

An object of the invention is to provide an improved mounting which willhave a and be adapted disconnection so that the opti'cian may rapidlychange the guards in fitting the glasses to the customer.

Another object of the invention is to provide a construction which shallhave its parts so located thatthef mounting will be inconspicuous uponthe wearer.

Still another object'is to provide a construction in which bearings ofmaximum size may be provided for the nose guards without rendering themounting conspicuous.

To these and other ends the invention consists in certain improvementsand combinations of parts, all as will be hereinafter more fullydescribed, the novel features bcing pointed outi in the claims at theend ofthe specification.

In the drawings: Figure 1 is an enlarged top view of a mountingconstructed in accordance with this invention, the lenses being shown asattached but broken away at their outer ends. Fig. 2 is a' front View ofthe same mounting partly in section. Fig. 3 is a vertical centralsection transverse of the plane of the lenses. Fig. 4 is a detail viewof one end of the mounting with the guard removed, and Fig. 5 isa'detail view of one of the guards. I

In the embodiment of the invention herein illustrated, the support forthe lenses A comprises an arched or bridging portion 1,

preferably connected to the arched or bridging portion 1 by horizontalconnecting portions 3 formed by providing arms on the blankSpecification of Letters Patent.

Original application filed June 21, 1907, Serial No. 380,027. Dividedand sem no. 526,094.

each having Patented Feb. 27, 1912. this application filed November 3,

from which the bridging portion 1 is made and rolling said arms toprovide vertical bearings 4, the arms being soldered or other wisesecured to the lens attaching devices 2. Arranged to operate on thesupport are nose guards comprising preferably levers a finger piece 6 atits forward end and a nose eiigaging member at its rear end formed withlower nose engaging pads 7 and upper nose engaging pads 8, the noseengaging member in this instance being formed in one piece of metal withthe lever 5, and to this end the metal is bent downwardly from the leverand thence upwardly to provide the lower loop 7, the upper end beingcarried above the lever and being enlarged toform the pad 8.

It will be noted that the lever portion of each nose guard has its flat.faces horizontally arranged. This arrangemcnthas become recognized asthe most desirable manner of making a fingei piece nose guard as itreduces the vertical height of the mounting in proximity to the lensattaching devices, but it has its disadvantages when the metal of thelever is cut to provide a hearing, for the. bearing thus formed is notof sufficient length and asa consequence the guard is unsteady on themounting. In this invention in order to overconie the unsteadiness of aguard formed as above set forth the latter is provided with a pivot pinor bearing 9 projectinglaterally from one of the flat faces of the lever5 to turn in the bearing 4: in the connecting portion 3, the lever alsocooperating with or seating-against the upper face or side of theconnecting portion. Of course, the connecting portion has greaterthickness than the lever and as a consequence the pivot pin may be givengreater length.

The guards are positioned or moved at their rear ends toward each otherby springs which in this instancefare carried by the support. Preferablythese springs are formed integral with the supports by providing arms onthe blanldfrom which the bridging portion is formed, these armsextending in opposite directions to the arms which form the (-(mncctingportions 3 and being located at the ends of the bridging portion. In thecompleted mounting each blank arm which is to form one of the springs isextended rearwardly, thence outwardly to a point bespring arm .ing thebearing on its guard in cooperatlon hind the proximate lensattaching'device 2 as at 10, thence forwardly and inwardly as at 11 toprovide a spring arm, said armpreferably being carried beneath thesupport so as to'lie on the opposite side thereof from the guard leverwhich it positions. This may also be utilized for retain- With one ofthe bearings 4 on the support and to this end it carries a hook member12 at.its forward end extending upwardly and over the guard lever 5 infront of the pivot of the latter.

It is apparent that the spring arms 11 act on thenguards in such amanner as to swing their nese engaging members toward each other,said'members being separated by moving theforward ends of the leverstogether.

In order to remove the guards for the re pair of the latter, or forfittlng the mounting,

'to a wearer, it is only necessary to displace the hooked ends of thespring from above the levers 5 when the latter may be removed.

An eye-glass mounting constructed in accordance with this invention'issimple in operation and inexpensive to manufacture. Owing to the form ofthe bearings greater steadiness in the mounting is obtained withoutincreasing the size of the latter. The springs have a maximum length andstrength and are so located that they are invisible from the front,except for small por tions thereof. These springs also serve forretaining the guards on the mounting and when the guards are removed thesprings remain with the mounting so that there is no liability ofmisplacing them. The mounting as a whole has no detachable fasteningdevices, except the lens screwswhich are necessary in all practicablemountings.

I claim. as my invention:

1. The combination with a' support for the lenses, of a nose guardcarrying a pivot pin turning in the support and detachable from thelatter with the guard, and a spring for positioning the guard secured toone of said parts and detachably interlocked With the otherto hold theguard on the support.
